I just got mine today, and I find this EVF to be really excellent. I was quite surprised at the quality in low light--I'm sure I'll be utterly poleaxed when I try it out in daylight. I think it may be a little clearer than the G1 version...at least in my G1, the display seemed a little bendy or something--it didn't appear perfectly flat and clear. This one does.
I am also really impressed with the stabilization on the E-P2, and find it to be a really handsome camera as well. My low light experiences suggest the inferior autofocus is overstated.
